Description

  The present invention relates to a connector having a half-fitting prevention function.

  Conventionally, what was described in following patent document 1 is known as an example of the connector provided with the half-fitting prevention function. As shown in FIG. 19, this includes a female housing 2 that can be fitted in the hood portion 1 a of the mating male housing 1, and a slider 3 that is slidably assembled back and forth while being in sliding contact with the upper surface of the female housing 2. The compression coil spring 4 is mounted while being sandwiched between the slider 3 and the female housing 2. When the housings 1 and 2 are fitted together, the slider 3 is pushed by the male housing 1 and retracted, and the compression coil spring 4 is elastically retracted by the retracting slider 3 to release the housings 1 and 2. Is accumulated. Therefore, when the fitting operation is interrupted in spite of the half-fitted state, both the housings 1 and 2 are forcibly separated by releasing the biasing force accumulated in the compression coil spring 4. The situation where both the housings 1 and 2 are kept in the half-fitted state can be prevented. The female housing 2 is provided with a restricting portion 5 that is slidable on the upper surface of the slider 3, whereby the slider 3 is displaced upward, restricting the lift and guiding the sliding operation. .

By the way, as shown in FIG. 20, the slider 3 is provided with a retaining projection 6 that can be latched with respect to the retaining member 7 provided on the female housing 2, whereby the slider 3 is assembled. It is designed to be prevented from slipping forward from the position. A taper-shaped guide surface (not shown) is formed on the rear surface of the retaining projection 6 so that the retaining projection 6 can be removed when the slider 3 is assembled to the female housing 2 from the front. It is easy to get over the stop receiving portion 7, and the assembly workability is good. In the assembled state, the retaining projection 6 is released into a relief groove 8 formed on the rear side of the retaining member 7.
JP 2002-246110 A

If there is a request to reduce the height of the connector described above, it is conceivable to omit the restricting portion 5. In that case, the displacement restriction of the slider 3 is performed by engaging the retaining protrusion 6 with the upper edge of the escape groove 8. However, since the guide surface is formed on the retaining protrusion 6 as described above, the area of engagement with the escape groove 8 is reduced by that amount, so that the displacement of the slider 3 is sufficiently reduced. There is concern that it will become impossible to regulate. On the other hand, simply increasing the size of the retaining protrusion 6 is not practical because it causes deterioration in assembly workability, and it has been difficult to deal with.
The present invention has been completed based on the above-described circumstances, and an object thereof is to sufficiently regulate the displacement of the slider while maintaining good assembly workability of the slider.

As a means for achieving the above object, the invention of claim 1 is directed to one connector housing out of a pair of connector housings that can be fitted to each other along the fitting / removing direction of both connector housings. A possible slider is assembled, and an urging means supported on one end side of the slider is provided. The other connector housing is provided with a pressing portion, and both sides of the slider are pressed by the pressing portion. The elastically deformable pressed arm is provided in a cantilevered manner, and the one connector housing is provided with a release guide portion capable of guiding the pressed arm to be elastically deformed. In this process, the pressed arm is pressed by the pressing portion, so that the urging means accumulates the urging force and the slider is initially moved. As the two connector housings are properly engaged with each other, the arm to be pressed is elastically deformed by the release guide portion to release the pressing state with the pressing portion, so that the slider moves forward. There is allowed, and so the biasing force of the biasing means is released, the slider stop ribs are provided projecting from said outer surface of the base of the pressure arm in the width direction towards The one connector housing has a relief groove that allows the retaining projection to escape, and a retaining member that can retain the slider in a retaining state by locking the retaining projection. Doo is provided, and the said stop ribs, guide surface capable guiding operation to overcome the retaining receiving portion during assembly of the slider is formed, the stopper collision part, the relief Slider is a regulating capable regulating unit from being moved in a direction intersecting the movement direction, and form had been chosen and assembling guiding portion in the height direction with the guide surface by engaging the peripheral edge, The overall height dimension is substantially the same as or slightly smaller than the escape groove, and the overall lateral dimension in the width direction is set to be equal to or less than the depth of the escape groove. The restricting portion projects outward from the guide surface, and has one side surface in the height direction and one side surface in the width direction that is substantially perpendicular to the height surface, so that it faces the peripheral edge of the escape groove. And is formed in a substantially rectangular parallelepiped shape that can be engaged, and a clearance in the height direction is secured between the escape groove and the retaining member, and when the slider is assembled, the clearance is Suppose that the restriction section is allowed to pass It has a feature in the roller.

The invention of claim 2 is the one described in claim 1, wherein the slider is mounted on one side surface in the height direction of the one connector housing,
The restricting portion is characterized in that it is provided on the side opposite to the mounting surface side of one connector housing of the retaining protrusion.

<Invention of Claim 1>
When the slider is assembled to one of the connector housings, the guide surface guides the movement of the retaining protrusion over the retaining member, so that the assembly workability is good. In the assembled state, the retainer protrusion is released into the escape groove and locked to the retainer receiving portion, thereby preventing the slider from coming off.
When both the connector housings are fitted, the urging means is pushed by the other connector housing, so that an urging force that causes the two connector housings to be detached is accumulated in the urging means. Therefore, when the work is interrupted even during the mating, both the connector housings are forcibly detached by releasing the urging force accumulated in the urging means, so that both the connector housings are half-fitted. The situation of being kept in a joint state is prevented. When the two connector housings are properly fitted, the urging force of the urging member is released by allowing the slider supporting the one end side of the urging means to move.

  According to the present invention, the restricting protrusion is provided with a restricting portion that protrudes outward from the guide surface, and the restricting portion engages with the peripheral edge of the escape groove so that the slider intersects the moving direction. Since the displacement is restricted, the engagement area with the escape groove can be increased by the amount of the restriction portion projecting from the guide surface, so that the displacement operation of the slider can be sufficiently restricted. In addition, assembling workability of the slider can be kept good by securing the guide surface as before.

<Invention of Claim 2>
Since the slider is easy to displace to the side opposite to the mounting surface of one connector housing, providing a restricting portion on the side opposite to the mounting surface side of the retaining protrusion ensures the displacement operation of the slider. Can be regulated.

  An embodiment of the present invention will be described with reference to FIGS. In this embodiment, the slider 40 and the compression coil spring S are assembled to the male connector housing 20 (hereinafter simply referred to as the male housing 20) that can be fitted to the female connector housing 10 (hereinafter simply referred to as the female housing 10).

The retainer 14 has a width direction between two positions, a temporary locking position (not shown) that allows the female terminal fitting 11 to be inserted and removed and a main locking position that locks the jaw 11d at the rear end of the main body 11a. It is possible to move along. The retainer mounting hole 13 is open on the upper surface of the female housing 10. On the upper surface side of the female housing 10, a pair of reinforcing portions 15 that bridge the front and rear hole edges of the retainer mounting hole 13 are provided. Reinforcement is achieved (FIGS. 2 and 13A).

  A pair of pressing portions 16 protrude from a position on the upper surface of the female housing 10 that faces the front of both reinforcing portions 15. The pressing portion 16 can press the pressed portion 46 of the slider 40 on the male housing 20 side, and the front end position thereof is a position slightly retracted from the front end of the female housing 10. A space is provided between the pressing portion 16 and the reinforcing portion 15 so that the pressed portion 46 can escape. Of the pressing part 16, the front surface 16a, which is a pressing surface for the pressed part 46, is formed in a reverse taper shape with an upward slope toward the front, and the rear surface 16b of the pressing part 16 has an upward slope toward the front. It is formed in a tapered shape. A lock portion 17 that can be locked to the lock arm 31 on the male housing 20 side is provided in a projecting manner at a substantially central position in the width direction on the upper surface of the female housing 10 and between the reinforcing portions 15 and the pressing portions 16. ing. The front surface 17 a of the lock portion 17 is formed in a taper shape that forms an upward gradient toward the rear in order to guide the climbing operation of the lock arm 31. Of the lock portion 17, the rear surface 17b serving as a locking surface for the lock arm 31 is set to face substantially straight along the vertical direction. A release groove 18 for allowing the elastic contact piece 27a of the short terminal 27 on the male housing 20 side to enter the front and lower sides of the front surface of the female housing 10 is located below the center and right cavities 12 shown in FIG. The elastic contact piece 27a can be pushed down by its peripheral edge.

  The male housing 20 is made of synthetic resin. As shown in FIGS. 3 to 8 and 13, the female housing 10 is fitted to the terminal housing portion 21 that can accommodate the male terminal fitting 25 and the short terminal 27. A semi-fitting prevention unit assembling part capable of assembling the slider 40 and the compression coil spring S functioning to prevent half-fitting on the terminal housing part 21 and the upper surface side of the hood part 22 while connecting the possible hood part 22 to the front and rear. 23. A bracket mounting portion 24 to which a bracket (not shown) can be mounted is provided on the left side surface of the terminal accommodating portion 21, the hood portion 22, and the half-fitting prevention unit assembly portion 23 shown in FIG.

  As shown in FIG. 7, the terminal accommodating portion 21 is provided with three cavities 26 in which the male terminal fittings 25 can be inserted from the rear side by side in the width direction. The male terminal fitting 25 includes a tab 25a that is in electrical contact with the female terminal fitting 11 in order from the front side, a substantially box-shaped main body portion 25b, and a barrel portion 25c that is crimped and connected to the end of the electric wire W. In the terminal accommodating portion 21, a short terminal accommodating chamber 28 that can accommodate a short terminal 27 is provided laterally and open below the center and left cavity 26 in FIG. 3. The short terminal 27 includes two elastic contact pieces 27a that protrude toward the hood portion 22 and that can elastically contact the lower surface of the tab 25a, so that the corresponding two male terminal fittings 25 can be short-circuited. . Each cavity 26 is provided with a locking groove 26a that can lock the lance 25d of the main body 25b, and the terminal accommodating portion 21 can be fitted with a retainer 29 that can be locked to the jaw 25e of the main body 25b. A retainer mounting hole 30 is provided, but since these have the same structure as the female housing 10 side, detailed description thereof is omitted.

  As shown in FIGS. 3 and 7, the hood portion 22 is formed in a substantially rectangular tube shape that opens forward, and the upper portion thereof is cut out over a predetermined range to provide a cantilever-like lock arm 31. It has been. The lock arm 31 is disposed substantially at the center in the width direction of the hood portion 22 and intersects with the base position (the front end position of the terminal accommodating portion 21) in the vertical direction (the fitting / removing direction of the housings 10 and 20). The elastic deformation is possible along the direction of On the lower surface side of the lock arm 31, a groove portion 31 a that opens to the rear leaving the lock claw 32 at the front end portion is formed. The rear surface 32a of the lock claw 32 is locked to the rear surface 17b of the lock portion 17, so that both the housings 10 and 20 can be held in a fitted state. Since the rear surface 32a of the lock claw 32 is formed in a taper shape that forms an upward slope toward the rear, when a force more than a predetermined level is applied to separate the housings 10 and 20 from the locked state. The lock arm 31 is elastically deformed while automatically releasing the locked state. That is, the locking structure between the lock arm 31 and the lock portion 17 is a so-called semi-lock structure. Further, the front surface 32b of the lock claw 32 is formed in a tapered shape having an upward slope toward the front so as to guide the ride on the lock portion 17.

  The pressed arm 45 of the slider 40 can enter the cutout space on both sides of the lock arm 31 in the hood portion 22 (FIG. 9). A pair of release guide portions 33 that can be engaged with the pressed arm 45 are provided at positions on both sides of the lock arm 31 at the upper edge portion of the terminal accommodating portion 21 (FIG. 13A). The release guide portion 33 is formed in a taper shape having an upward slope toward the rear, and can be guided to elastically deform the pressed arm 45 as the slider 40 moves backward as will be described later (FIG. 17). (A)). An escape recess 34 is formed on the bottom surface of the inner peripheral surface of the hood portion 22 for allowing the distal end portion to escape when the elastic contact piece 27a is elastically deformed.

  The half-fitting prevention unit assembling part 23 rises from the upper surfaces of the terminal accommodating part 21 and the hood part 22 and extends forward and backward, and a rear wall 36 connecting the rear end parts of both side walls 35. The compression coil spring S and the slider 40 can be assembled to the space surrounded by the both side walls 35 and the rear wall 36 from the front. As shown in FIGS. 5 and 7, the compression coil spring S is supported at the rear end by being received by the rear wall 36, and the front surface of the rear wall 36 is located in the rear end portion of the compression coil spring S. A spring holding portion 36a to be inserted and a substantially cylindrical (see FIG. 3) spring protection wall 36b covering the outer peripheral side of the rear half portion of the compression coil spring S are projected. As shown in FIGS. 3 and 4, a pressing portion 35a capable of pressing the upper surface side of the slider 40 projects inward from the rear upper ends of the side walls 35 and is longer than the spring protection wall 36b. Has been.

  As shown in FIGS. 3, 5, and 7, a pair of release grooves 37 for releasing a retaining protrusion 47 of the slider 40, which will be described in detail later, are opened on the opposite surfaces (inner surfaces) of the side walls 35. In the vicinity of the front end position thereof, a stopper receiving portion 38 that can be locked to the stopper protrusion 47 is provided so as to protrude. The retainer receiving portion 38 has a height dimension of about 2/3 of the escape groove 37, and its lower end is connected to the lower edge of the escape groove 37, and therefore the upper edge 37 a of the escape groove 37. A predetermined gap (about the same as the height dimension of a restricting portion 49 described later) is secured between the upper surface of the retaining portion 38 and the retaining portion 38. As shown in FIG. 5, the retainer receiving portion 38 is formed in a substantially rectangular parallelepiped shape at the rear side, whereas the front side approximately 2/3 portion is inward as it goes to the front end side. Is formed in a substantially triangular shape with a flat cross-section in which the overhanging dimension is reduced. Accordingly, the front surface of the retaining member 38 is formed in a taper shape, and this is a guide surface 38a that can guide the operation of the retaining projection 47, which will be described later, into the escape groove 37. Further, the distance between the guide surfaces 38a of both retaining stoppers 38 gradually increases from the rear end side to the front end side. Of the retaining stoppers 38, the rear surface 38b, which is a locking surface with the retaining protrusion 47, is formed straight along the vertical direction and the width direction, as shown in FIG. The side walls 35 are formed one step higher than the front half so that the rear half is almost the same height as the slider 40 to which the rear half is mounted.

  The slider 40 is made of a synthetic resin and includes a slider body 41 having a substantially flat plate shape extending forward and backward as shown in FIGS. 3 and 4. When the slider 40 is mounted on the half-fitting prevention unit assembly portion 23, the slider 40 is slidably in contact with the inner surfaces of the side walls 35 and the upper surfaces of the terminal accommodating portion 21 and the hood portion 22 (lock arm 31). 10 and 20) (moving / detaching direction).

  The slider body 41 is set such that its width dimension is substantially the same as or slightly smaller than the distance between the inner surfaces of the side walls 35. At the substantially center in the width direction on the lower surface of the slider main body 41, an overhanging portion 42 that protrudes downward in a stepped manner is provided while ensuring a permissible space that allows bending deformation of the lock arm 31 on the front end side (see FIG. 16 (B)). The lower surface of the overhanging portion 42 can be slidably brought into contact with the upper surfaces of the lock arm 31 and the terminal accommodating portion 21 in the assembled state. On the other hand, in the rear half of the upper surface of the slider body 41, as shown in FIG. 7, an operation portion 43 capable of pulling the slider 40 is formed so as to project to almost the same position as the upper ends of the side walls 35 in the assembled state. ing. As shown in FIG. 4 and FIG. 7, relief portions 43 a are formed on both side edges of the operation portion 43, and a pressing portion 35 a of the male housing 20 can enter here. As shown in FIGS. 6 and 13B, a protective wall relief 44 for releasing the spring protective wall 36b of the male housing 20 has a predetermined depth on the rear surface of the slider body 41, the overhanging portion 42, and the operation portion 43. It is formed. The back surface (rear surface) of the protective wall relief 44 can be supported by receiving the front end side of the compression coil spring S, and a spring holding portion 44a inserted into the front end portion of the compression coil spring S is provided there. ing.

  As shown in FIGS. 3 and 7, a pair of pressed arms 45 are provided so as to protrude from both sides (positions on both sides of the overhanging portion 42) at the front end of the lower surface of the slider body 41. The pressed arm 45 is formed in a cantilever shape extending rearward and is elastically deformable up and down with its base end (front end) as a fulcrum. The distance between the inner surfaces of the pressed arms 45 is set to be approximately the same as or wider than the width dimension of the lock arm 31. At the free end (rear end) of the pressed arm 45, a pressed part 46 having a substantially bowl shape is provided so as to protrude downward. Of the pressed portion 46, the front surface 46a that can be pressed by the pressing portion 16 on the female housing 10 side is formed in a reverse taper shape along the front surface 16a of the pressing portion 16, as shown in FIG. This ensures that the pressing portion 16 is pushed in. Of the pressed portion 46, the rear surface 46 b that can be engaged with the release guide portion 33 of the male housing 20 is formed in a tapered shape along the release guide portion 33. The pressed portion 46 rides on the release guide portion 33 and can smoothly guide the operation of the pressed arm 45 elastically deforming.

  In the initial position where the slider 40 is assembled to the half-fitting prevention unit assembling portion 23, the front end position is substantially aligned with the male housing 20, as shown in FIGS. The protruding portion 42 is disposed so as to block the bending space above the lock arm 31, and the bending deformation can be restricted. In this initial position, the rear end portion of the slider 40 is pressed by the front end portion of the pressing portion 35a entering both the escape portions 43a of the slider 40 (FIG. 10). Further, the front end portion of the spring protection wall 36b enters the protection wall relief portion 44, so that the compression coil spring S is covered over the entire length by the peripheral portions of the spring protection wall 36b and the protection wall relief portion 44 (FIG. 11 and FIG. 11). FIG. 13B). Further, at the initial position, the compression coil spring S is slightly elastically compressed, so that the slider 40 is prevented from rattling back from the initial position.

  Now, in the state where the slider 40 is assembled at the initial position, as shown in FIG. 11, the retaining projection 47 provided so as to project laterally from the outer surfaces of the pressed arms 45 of the slider 40 is a male housing. The slider 40 can be held in a state in which the slider 40 is prevented from slipping forward from the initial position by engaging with the retaining stopper 38 on the 20 side. Of the retaining protrusions 47, the front surface 47a, which is a locking surface for the rear surface 38b of the retaining member 38, is formed as a straight surface along the vertical direction over the entire height dimension.

  As shown in FIGS. 3, 7, and 8, the retaining protrusion 47 is set to have an overall height dimension that is substantially the same as or slightly smaller than the escape groove 37 of the female housing 10. Among these, about 2/3 of the lower side is an assembly guide portion 48 having substantially the same height as the retaining stopper portion 38, and about 1/3 of the upper side is relative to the upper edge 37 a of the escape groove 37. It is set as the restricting part 49 which can be engaged. In other words, the restricting portion 49 is provided on the side opposite to the upper surface, which is the mounting surface of the slider 40 in the male housing 20, in the retaining protrusion 47. In addition, the overall projecting dimension of the retaining protrusion 47 is set to be substantially the same as or shallower than the depth of the escape groove 37. The overall length dimension of the retaining protrusion 47 is set to a size such that the operating force required for assembly is less than or equal to a predetermined reference value.

  The assembly guide portion 48 has a substantially rectangular parallelepiped portion on the front side, whereas the outward projecting dimension decreases as the rear portion about 2/3 moves toward the rear end side. Therefore, the rear surface of the assembly guide portion 48 is formed in a tapered shape. The rear surface of the assembly guide portion 48 is in sliding contact with the guide surface 38a of the retainer receiving portion 38 when the slider 40 is assembled, thereby guiding the operation of the retainer protrusion 47 over the retainer receiving portion 38. 48a. Thereby, the operation force required for assembling the slider 40 can be reduced. Further, the distance between the guide surfaces 48a is gradually reduced from the front end side toward the rear end side.

  The restriction part 49 has a substantially rectangular parallelepiped shape as a whole, and is configured to project outward from the guide surface 48a. As shown in FIG. 12, the upper surface 49a of the restricting portion 49 can be engaged with the upper edge 37a of the peripheral edge of the escape groove 37, so that the slider 40 moves upward (the slider 40 The movement in the direction intersecting the movement direction) can be regulated. The upper surface 49a of the restricting portion 49 has a quadrangular shape in plan view, and the area thereof is increased by the amount that the restricting portion 49 protrudes from the guide surface 48a as compared with the lower surface of the assembly guide portion 48. The restricting portion 49 has a rear surface that is formed straight along the vertical direction and is not formed in a taper shape. However, when the slider 40 is assembled, the retaining portion 38 and the upper edge 37a of the escape groove 37 Since it is possible to pass through the gap between the two, there is no increase in operating force required for assembly.

  This embodiment has the structure as described above, and the operation thereof will be described subsequently. When assembling the male connector side, the male terminal fittings 25, the short terminals 27, and the retainers 29 are attached to the male housing 20, while the compression coil spring S and the slider 40 are placed in the half-fitting prevention unit assembling portion 23. Assemble sequentially from the front. When the compression coil spring S is inserted into the spring protection wall 36b, the spring holding portion 32a is inserted into the rear end portion of the compression coil spring S as shown in FIGS.

  Subsequently, when the slider 40 is assembled, both the pressed arms 45 enter the spaces on both sides of the lock arm 31 and the overhanging portion 42 is in sliding contact with the upper surface of the lock arm 31. When the slider 40 reaches a predetermined position, the guide surface 48a of the retaining projection 47 abuts on the guide surface 38a of the retaining member 38, and when the slider 40 is further retracted from this state, the guide surfaces 48 By being brought into sliding contact with 38a and 48a, the retaining projection 47 gets over the retaining member 38 and enters the escape groove 37, and the slider 40 reaches the initial position. The operating force at this time is reduced compared with the case where the guide surface is not set. At this time, as shown in FIGS. 11 and 12, the front surface 47 a of the retaining projection 47 abuts against the rear surface 38 b of the retaining member 38, whereby the slider 40 is held in the front stopped state from the initial position. Alternatively, the compression coil spring S may be assembled to the slider 40 side, and then both may be assembled to the half-fitting prevention unit assembly portion 23 at the same time. On the other hand, the female connector side is also assembled.

  Next, an operation for fitting both the housings 10 and 20 will be described. When the female housing 10 is fitted to the hood portion 22 of the male housing 20 from the state shown in FIG. 13 to a predetermined depth, the front surface 16a of the pressing portion 16 contacts the front surface 46a of the pressed portion 46 as shown in FIG. Is done. At this stage, the contact between the terminal fittings 11 and 25 has not yet started. When the fitting is advanced from this state, the pressed portion 46 is pressed by the pressing portion 16, so that the slider 40 moves backward from the initial position and the compression coil spring S accumulates the urging force as shown in FIG. 15. It is compressed while. In this process, the contact between the terminal fittings 11 and 25 is started, and the overhanging portion 42 is retracted backward from the bending space of the lock arm 31.

  By the way, in spite of such a state in the middle of the fitting, there is a case where the fitting operation is interrupted by misunderstanding that the operator has properly fitted. In that case, the biasing force that has been accumulated in the compression coil spring S until then is released, and the pressed portion 46 of the slider 40 biased forward pushes back the pressing portion 16, whereby both housings 10, 20. Can be forced to leave. Thereby, the situation where both the housings 10 and 20 are kept in a semi-fitted state is avoided.

  When the fitting further proceeds from the state in which the front surface 32b of the lock claw 32 of the lock arm 31 is in contact with the front surface 17a of the lock portion 17 (FIG. 15B), as shown in FIG. It is elastically deformed upward while riding on the lock portion 17. In this process, the rear surface 46b of the pressed portion 46 is in sliding contact with the release guide portion 33, so that the pressed portion 46 rides on the release guide portion 33 and the pressed arm 45 moves upward (press release) as shown in FIG. Direction). At this time, as the fitting progresses, the pressed portion 46 is displaced upward, so that the contact area with the pressing portion 16 gradually decreases. Further, in this process, the elastic contact piece 27a of the short terminal 27 enters the release groove 18 of the female housing 10 and is pushed down by its peripheral edge, so that it is separated from the tab 25a and the short-circuit state of both male terminal fittings 25 is released. The

  When the two housings 10 and 20 are fitted to the normal depth, the lock claw 32 of the lock arm 31 gets over the lock portion 17 and, as shown in FIG. The rear surface 32 a is locked to the rear surface 17 b of the lock portion 17. At this time, the lock arm 31 is completely retracted from the space in front of the overhanging portion 42. On the other hand, the slider 40 reaches the position where the pressed portion 46 is released from the pressing portion 16 (press release position) and the pressed state is completely released along with the normal fitting, so that the slider 40 is allowed to move. Will be. Accordingly, the urging force of the compression coil spring S is released, and the slider 40 moves forward accordingly. When the slider 40 reaches the initial position, the retaining projection 47 abuts against the retaining receptacle 38, so that the slider 40 is stopped in front. In this regular fitting state, the overhanging portion 42 is disposed above the lock arm 31, whereby the elastic deformation operation of the lock arm 31 is restricted. Further, since the pressed portion 46 is released between the pressing portion 16 and the reinforcing portion 15, the pressed arm 45 is restored to a natural state.

  On the other hand, there are cases where both housings 10 and 20 are detached for maintenance or other reasons. In that case, the slider 40 is retracted from the initial position while the compression coil spring S is compressed by pulling the operation portion 43 of the slider 40 backward. In this process, the rear surface 46b of the pressed portion 46 is in sliding contact with the rear surface 16b of the pressing portion 16, so that the pressed portion 46 rides on the pressing portion 16 and the pressed arm 45 is elastically deformed upward. When the slider 40 reaches a predetermined position, the overhanging portion 42 retreats from the bending space of the lock arm 31, so that when further operating force is applied from this state, it is guided by the inclination of the rear surface 32a of the lock claw 32. Then, the lock claw 32 rides on the lock portion 17 and the lock arm 31 is elastically deformed, so that the holding state of both the housings 10 and 20 is released (see FIG. 17). By further pulling the slider 40 from this state, both the housings 10 and 20 can be detached.

  As described above, when the two housings 10 and 20 are fitted and detached, the slider 40 is moved back and forth. In this movement process, the slider 40 is displaced so that the entire slider 40 is lifted. There is a concern that it will cause trouble. However, on the front side of the slider 40, the upper surface 49a of the restricting portion 49 of the retaining projection 47 engages with the upper edge 37a of the escape groove 37, and on the rear side of the slider 40, the pressing portion 35a is the relief portion. By engaging with the upper surface of 43a, the upward displacement operation of the slider 40 can always be regulated. Thereby, the moving operation of the slider 40 becomes smooth, and the fitting / detaching workability can be improved.

  As described above, according to the present embodiment, the retaining protrusion 47 is provided with the restricting portion 49 protruding outward from the guide surface 48 a, and the upper surface 49 a of the restricting portion 49 is the periphery of the escape groove 37. Since the slider 40 is restricted from being displaced in the direction intersecting the moving direction by engaging with the edge 37a, the engagement area with respect to the escape groove 37 by the amount of the restriction portion 49 protruding from the guide surface 48a. Thus, the displacement operation of the slider 40 can be sufficiently restricted. The assembling workability of the slider 40 can be kept good by securing the guide surface 48a as before.

  Further, since the slider 40 is mounted on the upper surface side of the male housing 20, the slider 40 is easily displaced upward, but the restricting portion 49 is on the opposite side to the upper surface of the male housing 20 of the retaining protrusion 47. Since it is provided, the displacement operation of the slider 40 can be reliably regulated.
